I am sure that or someone else will come up with a solution in the near future for more “optimized settings” so we can get decent quality with decent build times. I guess that these boosted up settings like .15 static scale that increases build time a lot also increases some calculations(time) which does not really affect a noticeable difference. In other words , we are probably wasting a lot of building time, and we might not even know it. But then again I might be wrong.
However if this is the way how building times we be I will probably have to start looking into building a home render farm, something like has. Seems kinda expensive but it would probably worth it. I am curious if with that horsepower it took him 40-50 mins to build that apartment how long would it take with a single i7-4790k.
